a 4 I D ATTORNEYS c aim as ne and" desireb secure y T 'f mortar B. It isunderstood that when the projectile is fired the life line readilyuncoils as the wire cord E' is held fixed.

A cap F is used for closing the aperture A, the cap having a groove F atits inner face for the passage of the wire cord E, as will be readilyunderstood by reference to Figs. 1 and 6. The cap F fits loosely intothe aperture A and when the projectile 1s fired the wire cord E instraightening out exerts a pull on the cap F and thus dislodges the samefrom the base A so that the life line can readily run out of the openingA during the flight of the projectile.

By the arrangement described the burning charge is not liable to injurethe life line as the same is protected from the burning charge by thecap F, and the wire cord E is not liable to be injured by the saidburning charge owing to its being formed of metal.

Ti hen the projectile is fired out of the mortar or gun B it is notliable to tumble over during its flight as the pull on the life line isfrom the base end of the projectile. The life line can be readily filledinto the casing C by the manufacturer, and the filled easing can bereadily placed in position 1n the tubularbody of the projectile and theend D of the life line fastened to the head IV, as above explained.

In practice the projectiles are made in two or more different lengths toaccommodate longer or shorter life lines, thus enabling fife savers toselect a projectile according to the distance to be traversed by theprojectile. .It will be noticed that by the arrangement describedprojectiles with' solid shot and loose life lines are entirely dispensedwith and life savers can readily use the projectile in a mortar.

Having thus described my invention, I

Patent:

1. In means for carrying life lines, a projectile, a life line coiledwithin the projectile and formed of a series of coils one in front ofthe other, the terminal of the outer convolution of one coil beingconnected with the beginning end of the inner convolution of the nextfollowing coil, the projectile hav ing an apertured base for the passageof the life line, and a cap fitting loosely in the aperture in the baseand having a groove at its inner face for engagement by the life line.

2. In means for carrying life lines, a projectile having a tubular body,a casing fitting into the said tubular body, a life line coiled withinthe said casing and having its forward end anchored to the projectile,an apertured base plate for the rear end of the casing, and an aperturedbase plug removably secured to the rear end of the tubular body andengaging thebase plate of the casmg, the rear end of said life lineextending ing coil, and a cap fitting through the apertures in said baseplate and base plug.

3. In means for carrying life lines, a projectile having a recessleading out through its base, a casing fitting into the said recess, alife line coiled within the said casing and havingits forward endattached to the projectile, the said life line being formed of a seriesof-coils one in front of the other, the terminal of the outerconvolution of one coil being connected with the beginning end of theinner convolution of the next following coil, an apertured plate forclosing the base end of the casing, and an apertured base plug removablysecured to the base of the projectile, the life line extending throughthe said apertures in said plate and plug.

4. In means for carrying life lines, a projectile having a centrallyapertured removable base, and a life line coiled within the projectileand havin its forward end anchored to the projectile and having its rearend extending through the apertured base of the projectile, the lifeline being formed of a series of coils arranged one alongside the other,the terminal of the outer convolution of one coil being connected withthe beginning end of the inner convolution of the next following coil, awire cord connected with the beginning end of the coil in the base endof the projectile, and a closure for the aperture in the base of theprojectile, and having a groove for the passage of the wire cord.

5. In means for carrying life lines, a projectile, and a life linecoiled within the projectile and having its forward end anchored to theprojectile, a wire cord connected with the rear end of the life line inthe base end of the projectile, the base of the projectile having anopening through which the wire cord extends, the said projectile havinga eng Wise ex' "1;; v in t p p eral face, the said wire cord extendili r1 the said groove and having its outer end secured to a fixed support,and a cap for closing the opening in the base of the projectile, the capfitting loosely in said opening and having a groove at, its inner facefor the passage of the said wire cord.

6. In means for carryin life lines, a projectile having a tubular body,a head attached to the forward end of the said body, and an aperturedplug removably attached to the rear end of the said body, a casingfitlng into the said cylindrical body, a life line coiled within thesaid casing and having its forward end attached to the said head and itsrear end extending through the said apertured plug, the said life linebeing formed of a series of coils one in front of the other, theterminal of the outer convolution of one coil being connected with thebeginning end of the inner convolution of the next followloosely in theaperture of said plug and having a groove for the passage of the lifeline.

7. In means for carryin life lines, a projectile having a tubular iody,a head attached to the forward end of the said body and an apert-uredbase plug removably attached to the rear end of the said body, a casingfitting into the said cylindrical body, a life line coiled Within thesaid casing and having its forward end attached to the said head, thesaid life line being formed of a series of coils one in front ot theother, the terminal of the outer convolution of one coil being connectedWith the beginning end of the inner convolution of the next followingcoil, an apertured base plate for the said casing, a grooved cap forclosing the aperture in the said base plug, and a Wire cord attached tothe beginning end of the coil in the base end of the casing, the saidWire cord extending through the said base plate and the cap groove andthe said projectile havmg a lengthwise extending groove in itsperipheral face and the said wire cord extending along the said groove.

In testimony whereof I have signed my name to this specification in thepresence of
